Abstract：Objective To investigate the application value of MOSFET detector in the quality control of total body irradiation. Methods To demarcate the radiation dose of MOSFET detector with ionization chamber at 360 cm SAD. To detect the radiation dose of patients during total body irradiation by using demarcated MOSFET detector in order to control and reduce measuring errors according to the conversion relationship among incident surface, exit surface and intermediate layer of the model. Results Among all MOSFET detectors (10 cases), the maximum dose deviation (＜3%) can meet clinical requirements in 7 cases and the maximum dose deviation (＜3%) also can meet clinical requirements in 3 cases which are demarcated again. Conclusion The radiation dose can be monitored and measuring errors can be controlled with the application of MOSFET detector in total body irradiation.
